I own SPARK LPG.

As of now, Chennai does not have CNG option. In future it might. In that situation, what will be the answers for the following questions.

  • Can CNG directly used on LPG vehicles?
  • If not, what should be done in LPG vehicles to use CNG?
  • In that case, if we doing some modification to use CNG in LPG vehicle should it require and thing to be done with RC book.

Liquefied petroleum gas (LPG) and Compressed natural gas (CNG).

Liquefied petroleum gas - Wikipedia, the free encyclopedia
Compressed natural gas - Wikipedia, the free encyclopedia

LPG is used in domestic household for cooking purposes. They are available in the form of Pipeline and Gas Cylinders to consumers.

CNG is used as a fuel for driving Automobiles viz cars, buses, trucks etc. The CNG are available and filled by automobile drivers at Fuel filling stations viz Petrol, Diesel, Gas etc

In case LPG is experimented to use as a fuel for automobiles
and CNG is experimented to use as a fuel for cooking purposes
what will be the effects ?.

In case LPG is experimented to use as a fuel for automobiles
then the automobile will not start because the engine expects CNG
or the automobile will start but it will not give the desired speed, mileage etc ?.

In case CNG is experimented to use as a fuel for cooking purposes
then the consumer will not be able to cook food, boiling water, milk etc ?.

What will be the effects if they are tried alternatively for different purposes ?.


Thanks & Regards,

Both CNG and LPG are available at Mumbai since over a decade. The probable answers to your queries.

1. No
2.Remove LPG and install CNG
3.Yes. Cancel LPG endorsement and make fresh CNG endorsement.
